In 2006, I had a MMR (Measles, Mumps, Rubella) vaccination about two weeks before I had my first big sensory symptom. My hip went numb. About five months later I developed optic neuritis.

Until I got optic neuritis, I had no idea that it was MS. I'd been told the numb hip was a sprain by a PA, who told me to put heat on it...and she basically yelled at me when I told her that heat made it worse. (accused me of faking it)

After I got ON, a neuro told me that the numb hip was Meralgia Paresthetica...and about 3 or 4 months after that I was diagnosed with MS.
